Study Notes
Sets in Mathematics
- A set is a well-defined collection of distinct objects.
- Sets are typically represented by capital letters.
- The natural numbers are represented by the symbol ℕ.
Set Notation
- The natural numbers are typically represented in set notation as: ℕ = {1, 2, 3, ...}.
Characteristics of Sets
- Sets are well-defined: Each object in a set is clearly identifiable.
- Sets contain distinct objects: No object can appear more than once in a set.
- The order of objects in a set is not important.
Cardinality of a Set
- The cardinality of a set is the number of elements in the set.
- It is denoted by |S|, where S is the set.
Subsets
- A subset is a set where all elements are also contained within another set.
- A subset of set A is represented by the symbol A ⊆ B.
